Irritating

I am honestly not sure how ER Consulting charges, I feel their rates are too high. I went for a emergency check up at Mediclinic Trichardt and it did not take that long only about 1h30 because I had to wait for the doctor at the casualty. I was charged R1000, and my medical aid only paid R400 and the R600 I had to pay. Well I did not have a problem with that though I feel we are overcharge. So I got an invoice from them, I knew I will pay end of the month when I get paid. But nobody is so irritating like them, they will send you 5 sms's a day and 5 emails a day even call you to tell remind you that you owe them. Even if you spoke to the consultant and advise which day you going to pay that won't stop them from sending you sms's and emails, super irritating as if you owe them millions whilst they over charge you. You guys are so irritating, I paid you today this morning and I still get your ****** emails. I never want to come across you again. I pray to God for my health and not deal with again because it is not the first time.
